A flaw in SIM cards could allow malware infection and surveillance

﻿Vulnerability on SIM cards could potentially allow hijacking as warned by a security researcher. The Founder of Security Research Labs in Berlin, Karsten Nohl said that the flaw he identified in SIM cards could allow a number of illegal activities and affect about 750 million mobile users. This defect is used on billions of phones every day and even though the encryption method has been made stronger in the last decade, a lot of handsets still continue to go by the older standard.

As reported by CNET, Claire Cranton, GSM Association spokeswoman said the organization has already passed the results on the members of its group that use the older standard. “We have been able to consider the implications and provide guidance to those network operators and SIM vendors that may be impacted,” she said.
